aceacce Base or frame structure In the embodiment of the inventionillustrated in the drawings, the machine is shown as supported by abase, which comprises spaced transverse I-beams l0, cross-braced by tierods ll. Upon the upper face of the I-beam supports is a base plate l2having a form best shown in Fig. 2. The general contour of the plate, itwill be observed, includes a rear portion, the sides of which convergeto form a generally triangular section, and a forward section, the areaof which is widened to afford a support for the parison mold, later tobe described. It will be understood that the plate is securely bolted orwelded to the sub-support in order to afford a rigid frame or base forthe operating parts of the machine.

An integrally formed lug l3 projects rearwardly from the base plate 12and supports a vertically extending standard l4 which is bolted thereto,the said standard having a series of three U-shaped brackets l5, l6 andI1 formed integral with the rear wall thereof. These brackets constitutesupports for the cylinders of the air motors, and are in substantiallyvertical alignment but spaced at equally disposed horizontal elevations.There are two brackets I8 and I9 integrally formed with the front wallof the standard 14, spaced as shown best in Fig. 1. These bracketsprovide rear supports, respectively, for the opening mechanism for thetransfer device and for the finish mold.

A pair of laterally spaced columns 20 and 2| are bolted to and supportedby the base plate l2, said columns being mounted, respectively, at eachside of the plate, but spaced inwardly from the front edge thereof. Eachof the columns carries, at an elevation above the base plate, a bracketsupport 22, and 23, respectively, and upon these brackets is mounted aplate 24 constituting a support for the. parts of the machine, ashereinafter explained.

The plate 24 is in the form best shown in Fig. 5 from which it will beunderstood that it comprises a central section 24a, lateral arms 24!),and forwardly extending arms 240, having upstanding ears 24d, the latterconstituting brackets for supporting a shaft for the transfer mechanismlater to be described.

Parison forming device mold includes a yoke 29, the arms of which extendforwardly and are spaced, respectively, from the mold segments oppositethe rear quadrant thereof. The end of each arm is bifurcated, and ispivotally connected to a link 3| by a pin 32, which link, in turn, ispivotally connected with its mold segment, by an eccentric p'inextending through spaced flanges 33 on the wall of each mold section.

The shank of the yoke 29 extends rearwardly and into a cylinder housing34, and has a reduced portion that is embraced by a spring 35. The shankis held in adjustment by a nut 36, threaded on the end of the shank thatextends through the rear wall of the cylinder. The housing 34 ispreferably formed integral with a slide a member 31. The slide member isU-shaped in cross section and rides on a rail 38 that is T- shaped incross section. The slide is held in place by gibs 39 mounted on eitherside thereof, and bolted thereto by bolts 40. The slide is supported bya bracket or table 4! secured to the plate i2.

The slide 31 is operated by an air motor 42, connected with the slide bya connecting rod 43, provided with a turnbuckle connection 44 foradjustment.

While an air motor is shown, it will be understood that other types ofpower means for reciprocating the slide may be employed, such as powerdriven cams.

It will be understood that the blank mold is alternately opened andclosed to receive and release the parison in timed relation with thefeed of the gob, and the transfer device for the parison from theparison mold to the finish mold.

The parison mold has a circumferential series of vertical passageways45, extending upwardly from the lower edge of the mold segments, and

said passages communicate with a semi-annular recess 43 in each moldsection. A split neck ring 41 is mounted in the recess 46. The fit ofthe neck ring in the recess has sufficient clearance in order thatcommunication between the recess 46 and the passages 45 is maintained.

A combination suction and blow head (Figs. 11 and 12) is mounted belowthe lower end of the parison mold. This head comprises a housing 48,which is supported by a bracket 49, rigidly con nected with the frontedge of the plate 1.2. The housing 48 is provided with a central bore 59having an enlarged annular recess 5! from which a passageway 52 extendslaterally and communicates with a conduit 53. A second annular recess 54is formed in the housing 48, and extends radially from the central bore50. A passage 55 is connected into said recess 54, which passageconnects with a conduit 56 (Figs. Hand 18). An annular series of.passages 51 extend upwardly from the chamber 54, and communicate with acylindrical recess 59 formed in the top of the housing 49.

In the bottom section of the housing 48 is a cylindrical chamber59,'having a lateral passage 60, which is connected with a conduit 6|.The chamber 59 is closed by a head plate 62 bolted thereto which has apassageway 63 extending axially therethrough, which. passagewaycommunicates with a conduit 64.

A piston 65 is mounted in the chamber 59 and carries a piston stem 56that extends through an axial bore 59 formed in the housing. The pistonstem 66 has a bore 61 extending downwardly from the top wall thereof,and terminating about intermediate of its length. The lower end of thepassage formed by the bore 51 communicates with an annular series oflaterally extending passageways 69 and is adapted to be'brought into andout of communication with the chamber 5! when the piston stem 66 isreciprocated by the movement of the piston 65.

The plunger (Fig. 13) comprises a base section 59, having a cylindricalcavity 10 in its lower wall adapted to fit over the upper reduced end ofthe piston stem 66, with which it is connected by a pin 1 i In the upperwall of the chamber III is a series of obliquely extending passageways12. A plunger plug 13 is formed integrally with the top wall of the basesection 69.

A plunger ring shown in detail (Figs. 16 and 17) is mounted in therecess 53 in the upper wall of the housing 48.- This member comprises abase section and a flange is. The base section 14 has an enlarged recess7! in its bottom wall, and a series of upwardly extending divergingpassageways ll. Above the flange is a reduced portion I8 that developsinto an enlarged head I8, having lower inclined walls 80. Aseries ofpassageways. 8| extend laterally in crossed relationship through thinclined walls 80 of the head of the plunger ring, and communicate witha central bore 82. The top wall of the head 18 has a series of grooves83 therein. V A brief summary of the operation of the suction and blowhead follows. I

In Fig. 11, the parts are shown in a position for blowing the hollowparison, and in Fig. 12 the parts are shown in the position when themold is open. By reference to Fig. 11,-if it be assumed that the baiiieplate is in position to close the upper end of the parison mold and themold sections closed, the plunger ring is then raised to the positionshown in Fig. 11 by the action of closing the mold. This is because thelower mold opening has a circular side wall 84 that develops into aninclined wall 85. The inclined wall 85 cooperates by cam action with theinclined wall 80 on the plunger ring, so that initially before the moldreceives the mold charge the plunger ring is lifted from its seat, as isshown in Fig. 12, to the position shown in Fig. 11.

The next operation is the admission of pressure through the conduit 84,which drives the piston 85 upwardly in the piston chamber 59 carryingthe piston stem, and the plungeriupwardly, and forces the plug of theplunger into the opening in the neck ring. This movement of the pistonbrings the passages 68 intocommunication with the chamber 54 which, inturn, is also in communication with the passage 51, the recess 16, thepassages 11, and the passageways in the lower wall of the mold section45.

Likewise, communication is established from the passageway 68 throughthe bore 61 to the passageways 12 in the plunger. When this ad- Justmenthas been effected, suction is then imposed upon the chamber 54 throughthe conduit 56, exerting a vacuum pull in the passagewaysdescribed. Thisvacuum pull exerts itself around the neck ring through the passages 8|,across the top wall of the plunger ring through the passages l3, andaround the upper crown of the plug of the plunger in communication withthe opening 82. This action draws a portion of the mold charge intoclosed contact with the neck ring, and compacts the charge in theneck-of the parison. I

When this operation has been accomplished, pressure is thenestablished'through the conduit 6|, the passageway 60, and the chamber59, against the upper head of the piston 65 forcing the piston stemdownwardly, and thereby closing the communication between the passageway68 with the chamber SI, and establishing, com munication with thechamber 5|, the adjustment being as illustrated in Fig. 11. This actiondrops the plunger plug from the mouth of the mold opening. I

Pressure is then imposed on the chamber llthrough the conduit 53 and thepassageway 52,

89, and having a bottom wall 90. The lower part a parison. The blow iscontinued sufliciently to complete the formation of the parison againstthe mold wall, and to expel the plastic glass from the interior of theparison, thereby completing the parison to a hollow form.

It will be understood, of course, that this operation occurs while theupper end of the parison mold is closed by a baifle plate, theconstruction and operation of which will now be described.

It should first be noted that the parison mold is so disposed in themachine that it is free to receive in its open upper end, a mold chargedropped from above. After the mold charge has been received in the openupper end of the parison mold, the opening is closed by the baiile plateby moving. it from a position at the side of the mold to a position toclose the mold.

The mounting of the bailie plate, and the means for operating it,comprise a standard 88 supported by the base plate l2. The standardsupportsa cylinder 81, the upper part of which forms a piston chamber88, closed by a cylinder head of the cylinder 81 forms a skirt in whichthere is a cam slot 9|. Within the chamber 88 a piston 92 is mounted forreciprocation therein by air pressure. A conduit 93, through thecylinder head, serves to admit pressure to drive the piston downwardlyand to exhaust pressure when the piston is'moved upwardly. The conduitM,

entering the bottom of the cylinder, serves to drive the piston upwardlyand to exhaust the chamber below the piston when the piston is drivendownwardly.. The piston carries a stem 95 that extends through thebottom wall of the piston chamber and into the lower part of thecylinder81. -An arm 86 extends laterally from the piston stem and projectsoutwardly through the camslot ii. The arm 96 has bolted thereto a plate91, to the outer extremity of which and von the under face thereof issecured a baffle plate or head shown in detail in Fig. 21. It will beunderstood that it comprises a plate 98 and a downwardly projecting head99, having inclined side walls, and a convex bottom wall. Thebaf- .flehead is dimensioned and contoured to fltinto the upper mold openinglflll of the parison mold. The inoperative position of the 'baille plateis clearly indicated in Fig. 5, from which it will be understood that itextends forwardly of the ma-' of the upper opening of the ing the bailleplate arm downwardly and in a swinging motion laterally and backwardlyuntil it registers with the mold opening Hill and conwhich pressure isexerted by way of the bore in a imposing a pressure inltiallyon thecavity formed a by the plug of the plunger in the compacted tinneddownward movement of the piston firmly seats the baflle head in the moldopening.

The compacting and blowing of the hollow parlson, in the manner ashereinbefore described,

is accomplished while the baiile plate is in position, thereby sealingthe opening and serving to form the bottom wall of the bottle.

After the parison has been formed, pressure is admitted through theconduit to the chamber II, which exhausts through the conduit 83.Pressure below the piston releases the baiiie plate from the parisonmold opening and returns it to its inoperative adjustment.

After this operation has been accomplished, the next operation is theengagement of the formed parison by the suction head of the transferde-- vice, the structure and operation of which will next be described.

Transfer device The transfer mechanism comprises a shaft IOI rigidlysupported in the bracket 24d, formed on the plate 24. A casting, shownseparately in detail in Figs. 24 and 25, is rotatably' mounted in thisshaft. This casting comprises a cylindrical section I02, carried by theshaft IN. A pair of spaced ears I03 extend upwardly therefrom, andprovide means for connection with the power device.

The casting has a hollow extension I04 formed integrally with thesection I02, and disposed at one side thereof, as shown in full lines inFig. 24, and in section in Fig. 5. The extension I04 has an opening inits top wall, and a flexible suction conduit I is connected therein. Afront section I06 integrally formed with the section I04 is cylindricalin form and is also hollow and in direct communication with the chamberformed in the section I04. The section I06 is forward of the shaft IMand parallel therewith. The member I06 has a series of radial passagesI01 through the wall thereof. A shaft I08 extends axially through themember I06. The shaft I08 is supported for rocking movement in a journalI09 at one end of the member I06 and at the other end in a boss formedas a part of the suction head. By reference to Fig. 5, it will be notedthat the shaft I08 extends beyond each end of the section I06.

The suction head comprises a semi-cylindrical housing IIO with laterallyextending flanges III. This member is dournaled on the member I06 and isrecessed to form an annular chamber, which is in communication with thesuction chamber formed in the members I05 and I06 by means of thepassageways I01. A plate H2 is connected with the flanges III by boltsII3 that extend through flanged sleeves II4. Surrounding each of thesleeves I I4 is an expansion spring II5 that fits between the flange atthe top of each of said sleeves H4 and the top face of the respectiveflange III. It will be noted that the lower end of each of the sleevesH4 is mounted in an opening formed, respectively, in the flanges III,the diameter of which opening is slightlyin excess of the externaldiameter of the sleeves H4, and also that there is a slight clearanceb'etween the central boss of the plate H2 and the opening in the lowerwall of the member 0. Therefore, since the matchingfaces of the flangesIII and the plate I I2- are resiliently held together by theconstruction described, the plate II2 has a slight floating movement forcentering the suction head in the opening ofthe parison mold.

On the bottom of the plate H2, and formed integrally therewith, is anextension I I6 that has an annular flange 1, below which are inclinedwalls 0 dimensioned to fit in the opening in the upper end of theparison mold. The extension is preferably formed with a circular recessin its bottom wall between the edges of the wall H8, and in this recessis a plug N9, the lower wallof which is convex to extend downwardly intothe mold opening. The plug II! has an annular recess I therein, thelower walls of which are spaced to form passageways directly incommunication with the cavity in the parison mold. The plug H9 issecured in the recess by a set screw I2 I, so that it may be removed forreplacement or for cleaning. An angular series of passageways I22,formed through the upper wall of the plug I10 and through the wall ofthe plate 8 H2, afford communication with the chamber formed between themembers I06 and I I0 so that. when the suction head is adiusted to closethe parison mold top opening (Fig. '1), suction is directly impressedagainst the wall of the parison below the mold opening.

It will be understood that the suction head is brought into operationafter the parison has been blown and the baffle plate removed. Theoperating connection for moving'the suction head into and out ofposition includes a link I23keyed to the shaft I00, anda nut I24 isthreaded over the end of the shaft, said link I23 having a cam slot I25therein that fits over the roller I26, supported on a stud shaft I21,which stud shaft, in turn, is rigidly carried in a bracket I20 supportedby the plate 24. It will be understood that the shaft I08 also serves tohold the suction head on its mounting, as said shaft has a nut I20 onits left end that impinges against the end wall of the member IIO (Fig.6) and keys the shaft thereto.

The power means for operating the suction head includes a slide I30mounted on a rail I3I, supported on the bracket I8 at one end, and bythe plate 24 at the opposite end. The slide is mounted on the rail I3Iin substantially the same manner as the slide for opening and closingthe parison mold, as heretofore described.

The slide is also operated in a similar manner by an air motor I32connected with the slide by a connecting rod I33 provided with aturnbuckle connection I 34. The slide I30, however, has upstandingspaced ears I35, which connect one end of a connecting rod I36 therewithby a pivoted box joint I31. The connecting rod I36 may be provided witha turnbuckle connection I38 for adjustment purposes.

When the slide I30 is operated to the right (Fig. l) the suction head ismoved to position to close the upper opening of the parison mold. Whenthe slide is reciprocated in the opposite direction, the suction headmoves in an arcuate path finally 'bringing the parison into a positionto be embraced by the flnish mold (Fig. 23)

The stages of movement of the parison by the transfer device arediagrammatically illustrated in Figs. 26-28. In Fig. 26, the parison hasstarted its arcuate movement forwardly and upwardly. In Fig. 2'7, themovement has been partially completed, and in Fig. 28 final movement toposition for reception in the finish mold has been completed.

The transfer mechanism just described is an important and essential partof the present invention, as it obtains the advantage of permitting thehollow parison to be completed in the parison mold and the transfereffected by engaging the bottom of the parison solely by vacuum pull,and then, by means of the mechanism 116- of the parison to move on ashort arc with the lighter end of the parison taking the longer arcuatepath of movement. The parison is taken from the parison mold after ithas sufliclently set, so that centrifugal forces are insufllcient,because of the manner of transferring the parison, to distort theparison'or to deform it in any way before it is received'in the finishmold. The

advantages of the transfer mechanism will, therefore, be readilyunderstood.

Finish. mold ,The finish mold, it will be understood, is located at aninset position from the front of the machine, and at an elevation sothatfby a movement in an arc of substantially 180, the parison isbrought from its inverted position to a reverted position for receptionin the finish mold. The finish mold itself is of orthodox constructioncomprising mold sections I39 and I40. The mold halves have recesses toreceive and interlock with the extension H6 and its parts Ill and III!of the transfer suction head. The mold halves are mounted for swingingmovement to open and close the mold. There is a spaced pair of hingestraps MI. The hinge straps are pivotally supported on a hinge pin I42by a plate I43 supported between the columns 20 and 2 I.

Inasmuch as the mechanism for opening and closing the finish mold is asubstantial counterpart of the mechanism for opening and closing theparison mold, it is unnecessary to redescribe the structure, but similarparts have been designated as those parts were designated in theprevious description with the suffix a.

The blow head for the finish mold is shown in section in Fig. 22, andthe mounting therefor is 4 bracket I44, and a shaft I45 on which an armI46 is adjustably supported, the blow head being connected directly tothe outer extremity of the arm I46.

The blow head proper includes a housing I41, having a recess I48 in itsupper end, which is closed by an end plate I49 bolted thereto, andforming a piston chamber. A piston I50 is mounted in the piston chamberand carries a piston stem I which extends downwardly in a bore I52formed in the housing I41. The piston stem has an axial opening I53therein, which extends substantially intermediate the length of thestem. This opening communicates with a radial passage I54 through'thewall of the stem. This opening I53 and the passageway I54 providecommunication with a passage I55 in the housing, into which is connecteda pressure conduit I56 in which pressure is constantly maintained.Connected with the lower end of the valve stem is a blow head I51 havinga recess I58 in its lower wall that fits over and seals against theopening in the blow mold. The head I51 is connected with the stem" I5Iby a coupling I59.

The chamber I48 has passageways I60 and I6I at opposite ends thereof,said passageways being connected-with conduits I62 and I63fortheadmission and exhaust of pressure from the piston I chamber.

After the parison has been brought to position, and the finish moldclosed, the blow head is moved to close the open end of the finish mold,and over the openend of the parison by admission of pressure through theconduit I03, which forces the piston and the piston stem downwardlycarrying the head I51 into position. Thisdown- I55, connected with thepressure conduit I56.

'10 There is a passage I64 in the head I5! in alignment with passageI53, and branch passages I65 in said head that provide directcommunication with the open end of the parison. This provides fordirectly blowing the article to final form.

After the final blowing, the finish mold is opened and the articleremoved by any suitable takeout device.

Operation The operation of the machine has been partially described inconnection with the separate parts. will tend to clarify the. disclosureand to further explain the sequence and synchronism of the operation.

The initial adiustment'of the machine will be assumed to begin with theclosing of the parison mold, with the baiileplate in open adjustment,and the transfer suction head in raised position, it being understoodthat the closing of the parison mold effects a primary adjustment of thesuction and pressure head in the lower opening of the parison mold. Whenthe machine is in this adjustment, there is a free vertical passage forthe mold charge to enter the upper opening of the parison mold. When themold charge has been received in the parison mold, the baflle plate ismoved to closed adjustment in the manner already described. When thebaffle plate is in position to close the parison mold, the plunger israised and the suction or vacuum conduit is then opened, effecting thecompacting of the mold charge at the neck endof the parison.

Following the compacting of the parison, the plunger is depressed, the,suction or vacuum dis- An overall description of the operationcontinued, and pressure is applied through the I pressure head, asheretofore described. The baflle plate is then moved to open position.

These operations are timed topermit the parison to set by the formationof a skin or enamel in the manner well understood in the art. Thesuction head of the transfer device is then moved over the upper openingof the parison mold, and suction is applied to engage the upper end ofthe parison, followed by an opening of the parison mold. The suction onthe head of the transfer device is maintained, and the transfer deviceoperated in the manner heretofore described to move the parison in thearcuate path,

'thereby'presenting it in a position to be empreferably relieved. Theparison then rests onthe suction head, and projects from the top of themold, as'shown by Figs. 22 and 23. Thus the parison is given a lengthsubstantially equal to that of the finished ware. The finish preferablyprojects through the top of the blow mold, and is stabilized byinterengagement therewith. The blow head is operated to close the upperend of the finish mold, and the final blow given to the parison tocomplete the article.

It will be understood that as soon as the parison is removed from theparison mold and the transfer device elevated to clear the vertical pathto the open end of the parison mold, the parison mold is again closedand the operation described is continued in succession.

Reference to the diagrammatical Fig. 29 will clarify the operation ofthe entire machine. In

this view the movements of the principal parts are obvious from thearrows and legends thereon.

The three most important air valves, that is the blank mold blow valveA, the transfer vacuum valve B, and the blank mold vacuum valve aremounted on the base plate I! (Figs. 1 and 2). The control eflected bythese valves is clear from the drawings without additional detaileddescription.

While many of the parts of the structure have been described in specificdetail, it will be recognized that changes and modifications in thestructure may be made within the limits of the invention. It should beunderstood, therefore,

that the invention is not to be limited by specific description beyondthe scope of the claims.
